Abstract :
The performance of a digital computer system based on an 11-year database is analyzed, revealing some of the statistical patterns of computer interruptions (i.e. the time of occurrence of the interruptions) caused by computer operator errors. The significance of human errors in relation to all modes of computer system failures is discussed, along with a nonstationary model for estimating computer system reliability levels. A case study is presented to illustrate the application of the proposed model and existing reliability models, and an extensive list of references is provided
